Windows Phone App Studio Makes App Creation as Easy as Drag and Drop
Microsoft explains on their official developer blog:
Windows Phone App Studio is a free, web-based app creation tool designed to help anyone quickly bring an idea to life by applying text, web content, imagery, and design concepts to any one of a rich set of customizable templates. Getting started is easy - just create a Microsoft account, choose your template, and begin adding your content. Windows Phone App Studio does the rest. When you're app is ready to go, you can download the app to your own phone, or share it with others by publishing it to the Windows Phone Store.
While developers may not get much out of this latest release, individuals now have a way to create personalized apps regardless of their skill set. Not a bad option for Windows Phone users who wish they had an app that doesn't yet exist on their platform.
